It operates in medium power range from 25-600Vac, supporting a variety of high-power phase control applications. This module uses a bidirectional thyristor, also known as a TRIAC, for phase control. The T405-600H module is designed to increase reliability and avoid electrical noise. It is an excellent choice for a broad range of commercial and domestic applications.

Application Field

The T405-600H is mainly used in thermostats, motor speed controllers, lighting control, industrial equipment and high power switching applications. It offers an extensive application field and is often used together with other devices such as MOSFETs, CMOSs and transformers. The module is suitable for use in a wide range of situations, such as large-scale energy conservation projects involving street lighting, factory lighting and other public lighting systems. It eliminates the need for large start-up times and is a cost-effective solution for many control applications.

Working Principle

The TRIAC is a three-terminal device which contains two junctions: an anode and a gate. When the gate is given a triggering signal of sufficient voltage, it will turn on and electrically isolate the anode from the gate, resulting in a triode, making it become conducting. This conducts the electrical current from the anode to the gate and vice versa. This is called bilateral conduction. By controlling the triggering signal, the thyristor will automatically turn on or off and regulate the current in the circuit thus providing two way conduction.

The T405-600H module works by using two pairs of triggers that work in tandem to turn the device ‘ON’ or ‘OFF’. The module is triggered by applying a voltage of approximately 4V to the gate using one of the two pairs of triggers depending on the particular application. This triggers the thyristor to turn on in one direction and the current then flows through the circuit. When the voltage is removed, the thyristor turns off and no current flows.

The T405-600H is suitable for many commercial and domestic applications because it is cost-effective, reliable and highly efficient. It can be used for thermostats, motor speed controllers, lighting control, industrial equipment and high power switching applications, making it an ideal choice for a number of control applications.

In summary, the T405-600H is an advanced 4-pin module that uses a TRIAC for phase control. It is a cost-effective and reliable solution for many commercial and domestic applications. The module works by using two pairs of triggers that work together to turn it on or off and regulate the current in the circuit. It is an excellent choice for a wide range of applications.
